Deflection of a Center-Loaded Rectangular Beam

Education Level

Subject

Introduction

Imagine you are walking across a simple plank that spans a creek and you stop in the middle of the plank to enjoy the scenery. Consider the plank you are standing on. You will notice it is bowing a bit downward where you stand. If you were to change the dimensions, could you make the beam less flexible (more rigid)?

Objectives

Students will engage in an inquiry activity to develop a mathematical model based on observations (of their own devising) of the physical world.

Students will understand the factors that affect the deflection of a center-loaded rectangular beam, supported on both ends, including width, thickness, and length.

Students will construct a model representing the relationship of factors affecting the deflection of center-loaded rectangular beams.

Sensors and Equipment

This experiment features the following sensors and equipment. Additional equipment may be required.
